Configuring JavaScript Debugger

Debugging JavaScript injections in PyCharm is supported through the JavaScript Debugger.
The plugin is bundled with PyCharm and activated by default.
If not, enable it on the Plugins page of the Settings dialog box as described in Enabling and Disabling Plugins.

Debugging of JavaScript code is supported in the Firefox and Google Chrome browsers
by means of browser-specific JetBrains extensions. No special steps are required from your side to install or enable these extensions.
PyCharm does it for when you initiate a debugging session for the first time.

During a debugging session, PyCharm considers any injected JavaScript code in a Web page opened in the browser as subject for debugging.
This means that you cannot use the same instance of a browser for browsing and for debugging simultaneously.
For Google Chrome you can solve this problem by configuring PyCharm to use a separate Chrome user profile for debugging.

To configure settings required for debugging JavaScript code

Use the Built-in server port spin-box to specify the number of the port where the built-in web server should run by default.
During a debugging session, the Chrome extension will listen to this port.
If for some reason the default PyCharm port is already busy, PyCharm finds the closest available port and starts on it.
This results in a conflict: PyCharm is running on a "new" port while the Chrome extension still listens to the port
of a previously started product and fails to establish connection with PyCharm.
The conflict reveals when you initiate a debugging session from PyCharm: the extension fails to connect through the default port,
PyCharm waits for connection from the extension and displays the following message with the port number where it is actually running:

In the Value tooltip delay (ms) field, specify the time period between pointing at an object
and displaying the object's value in a tooltip.

Whether to display DOM properties in a tab or not.

Whether to display function values in a tab or not.
If you want the function values to be shown only for user-defined functions,
select the Show only user-defined functions.
(Otherwise, the function values will be shown for all function.)

Whether you want object node properties to be shown. If so, specify the properties.
Use and to manage the list of properties.

Whether you want the debugger to skip certain scripts. If so, specify URLs for the corresponding scripts.
Use and to manage the list of script URLs.
